Description

Technical Field

[0001] This invention relates to the field of instrument boxes, and more particularly to an explosion-proof instrument box. Background Technology

[0002] In numerous fields such as industrial automation, petrochemicals, mining, and energy, various precision instruments and equipment are widely used to monitor and control key parameters in the production process, such as temperature, pressure, and flow rate. These instruments and equipment are typically housed in instrument enclosures to provide necessary physical protection and environmental isolation, ensuring stable operation under complex and potentially harsh working conditions. Currently, the common instrument box heat dissipation methods on the market mainly include natural heat dissipation and forced air cooling. The air cooling method on the market generally introduces external air, which can easily introduce external dust and moisture, affecting internal electrical components and posing a risk of dust explosion. In addition, during industrial production, electrical faults, short circuits, and other reasons may cause a sudden and rapid increase in temperature inside the instrument box. When the temperature rises to a certain level, the gas inside the instrument box expands rapidly, and the pressure increases sharply, which can easily lead to an explosion. The door of the existing instrument box is only connected by a simple latch, and this is the most likely place to have problems in the event of an explosion. Therefore, how to solve this problem needs to be considered. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an explosion-proof instrument box. Compared with existing technologies, this instrument box improves the actual explosion-proof effect during use. In addition, the internal circulation active heat dissipation operation makes the overall heat dissipation more efficient, while avoiding the adverse effects caused by the introduction of external air.

The right space of the cooling box is connected to the inside of the shell through the second connecting pipe, and the middle space of the temperature-conducting pressure accumulator is connected to the middle of the rotating tube through the third connecting pipe. A pressure accumulator mechanism is located inside the temperature-conducting pressure accumulator and is used for preliminary heat dissipation to improve the actual heat dissipation effect. A protective mechanism is used to improve the explosion-proof effect of the shell.

[0005] Preferably, a support frame is installed at the lower end of the housing, and an L-shaped plate is fixedly connected to the lower end of the housing. The rotating tube located below passes through the L-shaped plate and is rotatably connected by a bearing.

[0008] Preferably, the pressure accumulator mechanism includes a piston rod slidably connected inside the temperature-conducting pressure accumulator cylinder. The lower end of the piston rod is elastically connected to the inner bottom of the temperature-conducting pressure accumulator cylinder via a first spring. Multiple temperature-conducting fins are fixedly connected at equal intervals on the outer wall of the temperature-conducting pressure accumulator cylinder. The output shaft of the drive motor is connected to the upper rotating tube via a synchronous transmission component. The synchronous transmission component includes two synchronous pulleys, which are respectively mounted on the output shaft of the drive motor and the upper rotating tube. The two synchronous pulleys are connected by a synchronous belt.

[0009] Preferably, a flow divider plate is fixedly connected to the inner right side wall of the housing, and a plurality of flow divider holes are provided on the left side wall of the flow divider plate. The other end of the second connecting pipe is connected to the interior of the flow divider plate.

[0010] Preferably, the protective mechanism includes a U-shaped guide frame fixedly connected to the upper end of the housing, three U-shaped reinforcing rods slidably connected to the U-shaped guide frame, three support blocks fixedly connected to the left and right side walls of the housing, two first notches opened on the inner walls of the left and right sides of the bottom U-shaped reinforcing rod, and second notches opened on the inner walls of the left and right sides of the middle U-shaped reinforcing rod, the multiple second notches cooperating with the upper and middle support blocks, the multiple first notches cooperating with the upper support block, and a folded cloth fixedly connected between every two U-shaped reinforcing rods.

[0011] Preferably, the upper end of the housing has a columnar groove, and a slidable piston block is provided in the columnar groove. The lower end of the piston block is elastically connected to the inner bottom of the columnar groove through a second spring. The inner bottom of the columnar groove is connected to the inside of the housing through a connecting port. An abutment post is fixedly connected to the upper end of the piston block. Through grooves are provided on the inner walls of both sides of the columnar groove. Two rectangular cavities are symmetrically opened in the housing. The through grooves pass through the two rectangular cavities. A rectangular sliding plate that can slide left and right is provided in each rectangular cavity. The opposite sides of the two rectangular sliding plates are elastically connected to the inner wall of the corresponding rectangular cavity through a third spring. Limiting posts are fixedly connected to the opposite sides of the two rectangular sliding plates. The other ends of the two limiting posts extend to the lower end of the bottommost U-shaped reinforcing rod. The opposite sides of the two rectangular sliding plates are connected by a pull rope. The middle space of the columnar groove is connected to the outside through an exhaust channel.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: 1. After the drive motor starts, the piston plate slides left and right inside the piston cylinder through the linkage mechanism of the drive disc, drive rod, and piston plate. In conjunction with the first and second one-way pipes, this draws some air from inside the housing and compresses it to the bottom of the heat-conducting accumulator. As the gas accumulates, the piston column moves upward, and the high-pressure gas returns to the housing through the third connecting pipe, rotating pipe, and cooling box, forming a circulating airflow. The semiconductor cooling component cools the circulating air, achieving efficient heat dissipation and ensuring that the electrical components inside the instrument box operate at a suitable temperature, thus improving equipment stability and reliability.

[0013] 2. During normal operation, the interior of the casing is under low pressure, while the bottom of the thermal accumulator is under high pressure. In the event of a short circuit or other sudden temperature rise inside the casing, the relatively small amount of gas inside results in a slower expansion rate and less sudden stress, thus reducing the possibility of explosion. Simultaneously, the low internal air content leads to a low oxygen content, further reducing the likelihood of spontaneous combustion and enhancing the safety of the instrument box.

[0014] 3. During compression, the gas at the bottom of the temperature-conducting accumulator rises in temperature, creating a significant temperature difference with the surrounding environment. Utilizing heat exchange, this results in a rapid cooling rate within the same timeframe. Subsequently, as the high-pressure gas is released to a low-pressure state, its temperature drops rapidly, far below its initial uncompressed temperature, achieving initial cooling. After a second cooling process by the semiconductor cooling element, the temperature is even lower, resulting in excellent heat dissipation upon entering the housing, effectively ensuring the normal operation of the components inside the instrument box.

[0015] 4. After the drive motor starts, it drives the rotating tube and the temperature-conducting accumulator to rotate through the synchronous transmission components. The temperature-conducting fins are fan-shaped, and the overall structure resembles an axial fan. When the temperature-conducting accumulator rotates, the rotation of the temperature-conducting fins generates an upward airflow, which promotes heat dissipation of the temperature-conducting fins and the temperature-conducting accumulator, further improving the heat dissipation effect of the high-pressure gas and enhancing the subsequent internal heat dissipation effect of the shell.

[0016] 5. During normal operation of the instrument box, the limit post restricts the movement of the U-shaped reinforcement rod, without affecting the normal opening and closing of the sliding door. When an internal electrical short circuit occurs, indicating an impending explosion, the internal temperature and pressure of the casing increase rapidly, triggering the protective mechanism. After the limit post is released, the U-shaped reinforcement rod moves downward under gravity, evenly covering the sliding door portion of the casing, reinforcing the door and reducing the possibility of it being blown open during an explosion. Simultaneously, the folded fabric between the U-shaped reinforcement rods unfolds, and the warning text painted on it alerts surrounding personnel to potential hazards within the instrument box, ensuring their safety.

[0017] In summary, the explosion-proof instrument box of the present invention achieves multiple beneficial effects, such as efficient heat dissipation, reduced explosion risk, safe and stable operation of equipment, and reminders of safety, through mechanisms such as heat dissipation circulation, pressure regulation, preliminary cooling, enhanced heat dissipation, and protective warnings. It has significant innovation and practicality. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Reference Figures 1-8 An explosion-proof instrument box includes a housing 1, a support frame 2 installed at the lower end of the housing 1, and an L-shaped plate 10 fixedly connected to the lower end of the housing 1.

[0022] As one embodiment of the present invention, a heat dissipation mechanism is also included. The heat dissipation mechanism includes a vertical plate 7 fixedly connected to the lower end of the housing 1. A piston cylinder 8 is installed on the right side of the vertical plate 7. The left side space of the piston cylinder 8 is connected to the bottom space inside the housing 1 through a first one-way pipe 42. A second one-way pipe 9 is connected to the left side space of the piston cylinder 8. A cooling box 16 is installed at the lower end of the housing 1. A semiconductor cooling element 23 is installed at the lower end of the cooling box 16. The semiconductor cooling element 23 is composed of a semiconductor cooling chip and a heat dissipation fan. This is the prior art, which can quickly cool the passing air. The heat dissipation fan can dissipate heat from the hot end to ensure continuous operation.

[0023] In one embodiment of the present invention, the cooling end of the semiconductor cooling element 23 extends into the interior of the cooling box 16. A temperature-conducting pressure-accumulating cylinder 14 is provided below the housing 1. Rotating tubes 19 are fixedly connected to both the upper and lower ends of the temperature-conducting pressure-accumulating cylinder 14. The lower end of the upper rotating tube 19 is sealed, while the upper and lower rotating tube 19 is open at both ends. The lower rotating tube 19 passes through the L-shaped plate 10 and is rotatably connected by a bearing. A rotary joint 26 is installed at the other end of each of the two rotating tubes 19. The other end of the first one-way tube 42 is connected to the lower rotary joint 26. The rotary joint 26 located at the top is connected to the left space of the cooling box 16 through the first connecting pipe 17. The right space of the cooling box 16 is connected to the inside of the shell 1 through the second connecting pipe 18. The middle space of the heat conduction and pressure storage cylinder 14 is connected to the middle of the rotating pipe 19 through the third connecting pipe 20. A diverter plate 27 is fixedly connected to the right inner wall of the shell 1. Multiple diverter holes 28 are opened on the left side wall of the diverter plate 27. The other end of the second connecting pipe 18 is connected to the inside of the diverter plate 27. By using the diverter plate 27 and the diverter holes 28, the actual heat dissipation can be more uniform.

[0024] As one embodiment of the present invention, a one-way valve is installed inside both the first one-way pipe 42 and the second one-way pipe 9. The flow direction of the one-way valve inside the first one-way pipe 42 is one-way into the piston cylinder 8 inside the housing 1, and the flow direction of the one-way valve inside the second one-way pipe 9 is one-way into the lower rotating pipe 19 inside the piston cylinder 8. Furthermore, by using this method, internal circulating air flow can be generated during actual operation.

[0025] In one embodiment of the present invention, a drive motor 11 is installed at the lower end of the housing 1, and a drive disk 13 is fixedly connected to the output shaft of the drive motor 11. A drive rod 22 is rotatably connected to the lower eccentric part of the drive disk 13. A piston plate 21 that can slide left and right is provided inside the piston cylinder 8, and the other end of the drive rod 22 is rotatably connected to the piston plate 21 on the right side.

[0026] In one embodiment of the present invention, a pressure accumulator mechanism is also included. This mechanism is located inside the temperature-conducting pressure accumulator cylinder 14 and is used for preliminary heat dissipation to improve the actual heat dissipation effect. The pressure accumulator mechanism includes a piston rod 24 slidably connected inside the temperature-conducting pressure accumulator cylinder 14. The lower end of the piston rod 24 is elastically connected to the inner bottom of the temperature-conducting pressure accumulator cylinder 14 via a first spring 25. The first spring 25 is a spring with a large stiffness coefficient to ensure a larger actual gas storage volume. Multiple temperature-conducting plates 15 are fixedly connected at equal intervals on the outer wall of the temperature-conducting pressure accumulator cylinder 14. These multiple temperature-conducting plates 15 are used for heat dissipation and are connected to the temperature-conducting pressure accumulator cylinder. All cylinders 14 are made of thermally conductive material. Furthermore, in this design, the thermally conductive sheet 15 is fan-shaped, and its overall structure resembles the shape of an axial fan. When the thermally conductive accumulator cylinder 14 rotates, the rotation of the thermally conductive sheet 15 generates an upward airflow, which promotes the heat dissipation of the thermally conductive sheet 15. The output shaft of the drive motor 11 is connected to the upper rotating tube 19 through a synchronous transmission component 12. The synchronous transmission component 12 includes two synchronous pulleys, which are respectively installed on the output shaft of the drive motor 11 and the upper rotating tube 19. The two synchronous pulleys are connected by a synchronous belt.

[0027] As one embodiment of the present invention, a protective mechanism is also included. This protective mechanism enhances the explosion-proof effect of the housing 1. The protective mechanism includes a U-shaped guide frame 4 fixedly connected to the upper end of the housing 1. Three U-shaped reinforcing rods 5 are slidably connected to the U-shaped guide frame 4. Three support blocks 3 are fixedly connected to the left and right side walls of the housing 1. Two first notches 40 are formed on the inner walls of the left and right sides of the lowest U-shaped reinforcing rod 5. Second notches 41 are formed on the inner walls of the left and right sides of the middle U-shaped reinforcing rod 5. The multiple first notches 40 cooperate with the upper and middle support blocks 3, and the two second notches 41 cooperate with the upper support block 3. When the limiting post 37 is released, the lowest... Because multiple first notches 40 are provided on the spiral reinforcement rod 5, it will pass through the two sets of upper support blocks 3 when it moves down, and finally contact the lowermost support block 3. Similarly, the middle spiral reinforcement rod 5 contacts the middle support block 3, and the upper spiral reinforcement rod 5 contacts the upper support block 3. The three spiral reinforcement rods 5 just evenly cover the sliding door part on the shell 1 for reinforcement. The three spiral reinforcement rods 5 adopt this method to make the force more even. In addition, after the spiral reinforcement rods 5 are separated, the folded cloth 39 will unfold. A folded cloth 39 is fixedly connected between every two spiral reinforcement rods 5. Warning text is painted on the folded cloth 39. When it is displayed, it can warn people around.

[0028] In one embodiment of the present invention, a columnar groove 6 is provided at the upper end of the housing 1, and a slidable piston block 31 is provided in the columnar groove 6. The lower end of the piston block 31 is elastically connected to the inner bottom of the columnar groove 6 through a second spring 30. The inner bottom of the columnar groove 6 is connected to the interior of the housing 1 through a connecting port 29. An abutment post 32 is fixedly connected to the upper end of the piston block 31. Furthermore, a groove can be provided at the upper end of the abutment post 32 to ensure its usability. Through grooves 33 are provided on the inner walls of both sides of the columnar groove 6. Symmetrically arranged inside the housing 1 are... Two rectangular cavities 35 are connected by a through groove 33. Each rectangular cavity 35 is equipped with a rectangular sliding plate 36 that can slide left and right. The opposite sides of the two rectangular sliding plates 36 are elastically connected to the inner wall of the corresponding rectangular cavity 35 by a third spring. The opposite sides of the two rectangular sliding plates 36 are fixedly connected to limit posts 37. The other ends of the two limit posts 37 extend to the lower end of the bottom loop-shaped reinforcing rod 5. The opposite sides of the two rectangular sliding plates 36 are connected by a pull rope 34. The central space of the columnar groove 6 is connected to the outside through an exhaust channel 38.

[0029] In this invention, the drive motor 11 starts, and its output shaft drives the drive disk 13 to rotate. Since one end of the drive rod 22 is rotatably connected to the eccentric part of the lower end of the drive disk 13, and the other end is rotatably connected to the right side of the piston plate 21 inside the piston cylinder 8, the rotation of the drive disk 13 will cause the drive rod 22 to move eccentrically, thereby pushing the piston plate 21 to slide left and right inside the piston cylinder 8. Using the first one-way tube 42 and the second one-way tube 9, some air inside the housing 1 can be drawn away, and this gas is forced into the bottom space of the temperature-conducting pressure accumulator 14. Gas accumulates at the bottom of the temperature-conducting pressure accumulator 14, and is compressed (by the first spring 25). Under the elastic action, as the gas continues to accumulate, the piston column 24 will still be pushed upward. When the piston column 24 is pushed upward to a position higher than the connection between the third connecting pipe 20 and the heat-conducting accumulator cylinder 14, the high-pressure gas is released through the third connecting pipe 20, enters the cooling box 16 through the rotating pipe 19 above, and finally returns to the interior of the shell 1 through the diversion plate 27 and multiple diversion holes 28, generating circulating air flow. During this process, the semiconductor cooling device 23 is activated, which can cool the circulating air and achieve cooling and heat dissipation of the circulating air. Furthermore, during the above process, the inside of the shell 1 will be under low pressure, while the bottom of the heat-conducting accumulator cylinder 14 will be under high pressure. In this way, if a short circuit or other sudden temperature rise occurs inside the shell 1 later, the expansion speed will be relatively slow due to the small amount of gas inside, and the sudden force will not be too great, thus reducing the possibility of explosion. In addition, the low air content inside the shell leads to a low oxygen content, making it less likely for spontaneous combustion to occur. In addition, since the bottom of the heat-conducting accumulator cylinder 14 is under high pressure, the gas compression temperature rises, causing the temperature of this part of the gas to rise rapidly. The temperature difference with the surrounding environment is large. By using heat exchange, the cooling speed is faster in the same amount of time. When the high-pressure gas is released to a low-pressure state after cooling, the temperature drops rapidly, far below the initial uncompressed temperature, achieving initial cooling. After secondary cooling by the semiconductor cooling element 23, the temperature is low. After entering the shell 1, the heat dissipation effect is excellent. After the drive motor 11 is started, the upper rotating tube 19 drives the temperature-conducting accumulator cylinder 14 to rotate through the use of the synchronous transmission component 12. The temperature-conducting fin 15 is fan-shaped, and its overall composition is similar to the shape of an axial flow fan. When the temperature-conducting accumulator cylinder 14 rotates, the rotation of the temperature-conducting fin 15 will generate an airflow from bottom to top, which will promote the heat dissipation of the temperature-conducting fin 15 and the temperature-conducting accumulator cylinder 14, further improving the heat dissipation effect of the high-pressure gas, and further improving the heat dissipation effect inside the subsequent shell 1. It should be noted that when the instrument box is operating normally, the limit post 37 limits the bottom loop reinforcement rod 5, and the three loop reinforcement rods 5 are in a separated state, which does not affect the normal opening and closing operation of the pull-up door of the housing 1. If an internal electrical short circuit occurs and there are signs of an impending explosion, the internal temperature of the housing 1 will suddenly rise and the internal pressure of the housing 1 will increase sharply. Under the action of pressure, the piston block 31 in the columnar groove 6 will overcome the elastic force of the second spring 30 and slide upward, driving the abutment post 32 to move upward. The upward movement of the abutment post 32 will pull the pull rope 34, and the pull rope 34 will drive the two rectangular slide plates 36 to move closer to each other, causing the third spring to be compressed. The rectangular sliding plate 36 moves the limiting posts 37 closer together, releasing the restriction on the bottom loop-shaped reinforcing rod 5. After the limiting posts 37 are released, the bottom loop-shaped reinforcing rod 5 moves down under the action of gravity. Due to the first notch 40 opened on its left and right inner walls, it will pass through the two sets of support blocks 3 above and finally contact the bottom support block 3. Similarly, the middle loop-shaped reinforcing rod 5 contacts the middle support block 3, and the upper loop-shaped reinforcing rod 5 contacts the upper support block 3. The three loop-shaped reinforcing rods 5 just evenly cover the sliding door part on the housing 1, reinforcing the sliding door and reducing the possibility of the sliding door being blown open in the event of an explosion. A folded cloth 39 is fixedly connected between every two loop-shaped reinforcing rods 5. When the loop-shaped reinforcing rods 5 separate and move down for reinforcement, the folded cloth 39 will unfold. The folded cloth 39 is painted with warning text, which can warn the surrounding personnel and remind them to pay attention to the possible dangers in the instrument box.
